Filed: 1983-04-20
Abstract: PURPOSE:To economize a conduction/crosstalk testing device by decoding a test signal transmitted to a core of a cable and an output signal obtained by receiving said test signal in the same format and comparing the codes of both signals. CONSTITUTION:When a switch circuit 4 sets up the number of cores of the cable 1 and sends a start signal to a control circuit 5', the circuit 5' sends a forward signal to a counting circuit 6 and the circuit 6 outputs an output code to a decoder 7. The decoder 7 converts the code and sends selected signals for respective cores successively to the cores 1-1-1-4 through gates 8-1-8-4 and a connector 2. The transmitted signal is received by gates 10-1-10-4 successively through a connector 3 and the outputs of the gates are sent to an encoder 19. The encoder 19 decodes the received signals in the same format as the output code of the circuit 6. A comparator 20 compares the decoded code with the code of the circuit 6 and the circuit 5' decides the quality of the cable 1 on the basis of coincidence/dissidence of the compared result and displays the decided result on a display device 17. A comparator 18 compares the set value of the circuit with the value of the circuit 6, and when both the values coincide with each other, the test is ended.

Title: Method for predicting flash-over in snowed insulator
Inventor: HATAKEYAMA TAKASHI
IPC: H01B17/00
Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a method for predicting flash-over in snowed insulator at relatively early stage with high estimated probability. SOLUTION: Leak current in snowed insulator is sampled (S1), the sampled value and the phase of the leak current is stored with reference to the timing at voltage phase 0 degree applied thereto (S2). For each half period of the leak current, leak current is determined to be 'spike current disappearance' whether the peak phase of the sampled value is in the range of 45 degrees from 0 or 180 degrees (S3). Then the average of the number of 'spike current disappearance' for a predefined period of time and the peak value of leak current out of the range of spike current disappearance is determined (S4).  Then the number of 'spike current disappearance' in which the peak values for a predetermined period of time are below the predetermined threshold is determined (S5), a predictive signal of occurrence of flash-over based on the time lapsed of the number of 'spike current disappearance' during a predetermined time of period (S6).

Title: Switch mechanism of time informing watch
Inventor: ABE HIDEKI
IPC: G04C23/22
Filed: 1978-06-08
Abstract: PURPOSE: To operate a lead switch reliably irrespective of a ringing time by connecting the leading end portion of an adjusting lever, which has its base portion fitted freely on a cam eccentrically attached to a shaft, rotatably to the center of an OFF switch lever.  
     CONSTITUTION: If an eccentric cam 27 is turned in order to change the conducting time of a lead switch 1, an adjusting lever 31 is moved longitudinally while having its base portion moving up and down. This vertical movement of the base portion takes place about a connecting pin 33 so that it is not bransmitted to a lever 5 but is transmitted in the perpendicular direction to a shaft 26. As a result, the lever 5 is moved only in the longitudianl direction by the movement of a slot 32 along the shaft 26 so that the leading end portion of an ON switch lever 3 is left vertically stationary even if the cam 27 is turned to any position. As a result, even if the eccentric cam is turned to change the ringing time, the ON and OFF operations of the lead switch can be performed without fail.

Then the repetitive switching to the division ratio N1 or N2 is kept until the signal within the pass band of the filter 6 is obtained and the comparator detects the same phase.
